In the past, it was very laborious to use sandstone for building purposes, because the cutting machine and processing machinery and equipment in the quarry were relatively backward. In recent years, these conditions have been improved, and we can gradually provide customers with the highest level of professional knowledge and high-quality products according to their color requirements. Sandstone can be widely used. Some people even think that "everything you can think of can be used." Application example
Vases, bowls, utensils, tables, light bulbs, ashtrays, flower pots, chairs, panels, furniture, counters, benches, heaters, signboards, clocks, oil tanks, hand-held oil lamps, spray pools, columns, baths, tiles, ovens, arches, jars, waterfalls, oil paintings, railings, monuments, masks, tombstones, etc. The choice of general building stone ultimately boils down to personal favorite appearance, color, stone performance, convenience and reasonable cost. However, in many cases, performance means correct use, maintenance and selection of suitable coating method and thickness. In the past many years, many designers and engineers began to use natural stone in large quantities indoors and outdoors. Through sandstone design, material selection (including preparation, full management of various projects, full discussion, etc. ) and other processes have done a lot of detailed work and accumulated rich experience, providing the following reference. Tiles and curtain walls
The size range is 15mm(5/8 inch) to 500mm(20 inch) square, the recommended thickness is 20mm(3/4 inch), and the thickness of15mm is also acceptable. However, the decorative skirt building can only be used in skilled construction (indoor use only), because some constructions will have problems when the stone is too thin. It can be used for indoor and light-load business (no large-scale mechanical exchanges), and in any case, it must be very skilled in construction. We suggest using wet method or adhesive to complete the construction. Larger stones can only be used for curtain walls. If the construction method is correct, 20mm(3/4 inch) thick stone can be used indoors or in places where people come and go. If it is on the outdoor cement structure, it must be mixed with tile glue, sand and cement bonding auxiliary materials. Outside, if the stone with a size over 400mm( 16 inch) has insufficient adhesion, it will bend in hot weather. Indoor, stone with a size not exceeding 100mm( 1 1 square foot) can be used as floor material or curtain wall material. The thickness of 30mm( 1 1/4 inch) can be used indoors and outdoors, which is also the most suitable, and it can also be used in places with large traffic. If it is used as a motor vehicle lane, it needs to be built on a cement structure. Indoor is most suitable for casinos or crowded hotels (the construction need not be too elaborate). This thickness can be used for the top plate of furniture, and can also be used for panels over one square meter. If the stone is not more than 500mm, the special glue for swimming pool will not skew in hot weather. 40mm( 1 1/2 inches) thick stone can be used as indoor decoration material, and can also be used for external decoration of buildings without heavy objects (signboards, etc.). ) all hung up. You can also lay any road surface. Thin stones can be inlaid, and this thickness can be framed. In addition, it can also be used as a substitute for the thin stone mentioned above. 50 mm (2 inches) thick stone can be used for motorways, swimming pool bottoms and sidewalks, if it is on gravel. When used as a curtain wall material, it can be constructed by mosaic method without adhesive; The minimum building height of this thickness is more than one floor (mosaic construction method). Frame structure is recommended for external building materials exceeding 1 m. Stone slightly thinner than 75mm(3 inches) can be used for curtain walls that can withstand a certain pressure, highways that are directly laid on the ground after accurate calculation, and most of the curtain wall materials for external walls. 100mm(4 inches) thick stone can be used for walls or hollow walls that can withstand heavy pressure. Pile up like bricks. According to the size, columns, furniture, etc. There are various manufacturing methods. Columns can be made of all sandstone; Or hollowing out the center to form a hollow column to reduce the weight; It can also be divided into small pieces and then assembled into columns. Surface treatment and thickness usually vary with specifications, usage methods and usage occasions (indoor, outdoor, wall decoration materials, etc.). You can learn more about this information and matters needing attention from professional companies. Dirt and pollutants are not only ugly, but also contain aggressive chemicals, which will damage sandstone. Whether pollution occurs during construction or maintenance must be treated differently. Generally speaking, prevention is more important than cleaning, and the effect of daily long-term maintenance is better than sudden and acute cleaning. Through correct design and material selection, careful construction and maintenance, stains can be reduced and prevented. The so-called correct design is to pay attention to the pollution of sand and gravel products caused by the following things:
When products are processed on a flat surface, sandstone products are easy to be polluted, such as inclined wall cap stones, unnecessary parts of drainage by wall holes, structural parts where waterways flow into narrow places, and water flowing over the surface of concrete, glass or other building materials and onto the sandstone surface. Under special circumstances, materials that match the properties of stone materials should be selected. For example, when used as a wall lining, it is necessary to protect the front of the elevator, near the elevator switch and furniture. The combination of incompatible materials is easy to cause pollution. (For example, liquid leaks from the car to the surface of sand. Permeable mortar laid on the bridge deck or stairs will become coal pollution. Incorrect joint cleaning is also an important reason.
Correct treatment methods include careful attention to transportation, storage and construction. Thin panels are not only fragile, but also easy to get dirty. Attention must be paid to stubborn stains, such as mortar, paint, protective layer spots, scaffolding rust and mechanical lubricating oil.
From the storage period to the end of construction, the stone must be covered with plastic layer or anti-pollution cover cloth as far as possible. Fully understand that the whole service process may cause internal and external pollution due to pollution or human contact. It must be isolated from pollution sources as much as possible, and dirt should be removed frequently. In polluted areas, use appropriate paints and building cleaners to clean stains. When cleaning stone, it should be moderate to prevent damage to the environment and workers or loss to the stone itself. Considering the cost, cleaning should be economical and effective. Therefore, you must be familiar with the following:
1, convenient cleaning methods and places;
2, the ability to feel the loss of stone when cleaning;
3. The pollution degree of the surface;
4. Do you need cleaning?
